Description

  The present invention provides a fluorescent lamp with an auxiliary light source that detects vibration when an earthquake occurs and turns on the auxiliary light source.

  In recent years, large-scale earthquakes have occurred in Japan, and it is predicted that there is a high possibility that large earthquakes will occur in various places in the future. Because large-scale earthquakes occur day and night, if a large-scale earthquake occurs at night, the illuminance is low in the room after going to bed due to the lighting device turning off, so disaster prevention actions such as evacuation and confirmation of damage status It takes time to start. Disaster prevention action can be started if lighting equipment can be turned on after the earthquake has occurred to ensure illuminance, but in the event of a power outage due to a large-scale earthquake, it will be quick if light cannot be secured with an emergency portable light or candle. Because evacuation is not possible, there is a risk of increasing damage.

  Against this background, there is known a technique related to an illumination device that includes a vibration sensor and an illuminance sensor that detect vibration caused by an earthquake, and that turns on a light source when the occurrence of an earthquake is detected when the surroundings are below a certain illuminance (for example, patents) Reference 1). According to this prior art lighting device, even if the night lighting device is turned off, it controls to detect the vibration caused by the earthquake and turn on the light source. It becomes possible to do.

On the other hand, a fluorescent lamp is known in which an electric circuit including a storage battery or an electronic component capable of storing electric power is disposed in the base, and a light emitting diode that is turned on by the electric circuit is provided in the base (for example, , See Patent Document 2).
Japanese Patent Laid-Open No. 9-93832 (paragraph number 0012, FIG. 1) JP 2005-122907 A

  Since the illumination device disclosed in Patent Document 1 has the same light source that is turned on when an earthquake is detected and the light source that is turned on at normal time, lighting power for normal lighting is required even immediately after the occurrence of an earthquake. Therefore, a large-capacity storage battery that can supply lighting power equivalent to that during normal lighting is required even during a power failure. When a large-capacity storage battery is mounted, the lighting device is increased in size and the weight of the device is increased, which may limit the installation location. Moreover, in order to light a light source by the detection of an earthquake, it is necessary to newly install a dedicated lighting device including a control device such as a vibration sensor and a storage battery. Therefore, since the purchase cost of the new lighting device is increased, the conventional lighting device is difficult to spread.

  In addition, the fluorescent lamp disclosed in Patent Document 2 can turn on a light emitting diode by battery means disposed in the base immediately after the lamp is turned off or when a power failure occurs due to a disaster such as an earthquake while the lamp is lit. it can. However, this prior art does not disclose a method of turning on a light emitting diode when a power failure occurs due to an earthquake or the like while the lamp is turned off. In other words, even if a power failure occurs due to an earthquake or the like when the power supplied to the fluorescent lamp is off, it cannot be detected, so the light-emitting diode is turned on in response to the earthquake or the accompanying power failure while the lamp is extinguished. I can't let you.

  On the other hand, the present inventor has examined a fluorescent lamp with an auxiliary light source that can provide a vibration detection means in a lighting circuit of the light emitting diode, for example, and can turn on the light emitting diode for a predetermined time due to an earthquake even when the fluorescent lamp is turned off. is doing. The vibration detection means provided in this fluorescent lamp requires a standby current to flow through the auxiliary light source lighting circuit even when the lamp is turned off, but the battery means built in the base is disposed in a limited space. To be relatively small. Therefore, in order to suppress the power consumption of the battery means built in the base, the standby current flowing through the auxiliary light source lighting circuit is cut off before the user starts using the lamp or when it is not necessary to detect the earthquake. It is desirable to keep it.

  The present invention has been made in view of the above problems, and even when the lamp is extinguished, it is possible to detect vibration and illuminate with a predetermined illuminance when an earthquake occurs, and is inexpensive and relatively small in size. It is an object of the present invention to provide a fluorescent lamp with an auxiliary light source that can easily reduce the standby current flowing through the auxiliary light source lighting device when it is unnecessary and can suppress power consumption of the battery means.

  The fluorescent lamp with an auxiliary light source according to claim 1 is a glass bulb in which an electrode is sealed; a connection attached to the glass bulb, connected to an electrode and connected to a lead wire derived from the glass bulb, and arranged on the outer surface A base having a terminal; an auxiliary light source attached to the base so as to face outward from the outer surface of the base; a vibration detecting means and a battery means, and the auxiliary light source is connected to the battery means according to the detection of the vibration detecting means An auxiliary light source lighting device housed in the base to be turned on by the power of the base; and a control unit disposed on the outer surface of the base, and the power from the battery means is turned on according to the operation of the control unit Power supply opening / closing means for performing off-control;

  In the present claims and the following claims, the definitions of terms are as follows.

  The glass bulb functions so as to emit predetermined light by emitting light from a phosphor layer formed on the inner surface of a discharge medium such as mercury or a rare gas enclosed therein, where discharge is generated by an electrode. The shape may be a straight tube, an annular shape, a square shape, a bent tube, or the like.

  The base is attached to the glass bulb, and is configured in such a shape that the connection pin electrically connected to the electrode can be connected to the power supply terminal of the socket.

  The auxiliary light source is attached to the base so as to face the outer surface of the base so that visible light can be emitted to the outside, and it has less light output than the light emitted by the discharge of the glass bulb, but can be lit with relatively low power It is a small light source. For example, a light-emitting diode is optimal, but an electroluminescence element or the like may be used as long as the above conditions are satisfied.

  The auxiliary light source lighting device includes vibration detection means and battery means, and is mounted directly or indirectly in the base. The auxiliary light source lighting device performs on / off control so that the auxiliary light source is turned on by the electric power of the battery means according to the detection of the vibration detecting means. The vibration detection means is composed of a mechanical switch element such as a vibration switch or a piezoelectric element that can detect the occurrence of an earthquake according to the acceleration and vibration frequency of an earthquake shake, and generates a detection output in response to the detection of this element. In response to this detection output, the battery means operates to turn on a switch provided in the circuit so as to start supplying power to the auxiliary light source. In addition, although a semiconductor switch, a relay switch, etc. are used for this switch, in order to operate these switches, a standby current is required. Further, the vibration detection means may require a standby current. For this reason, the auxiliary light source lighting device requires a standby current supplied from the battery means regardless of whether the vibration detecting means is mechanical or electric.

  The battery means may be a secondary battery that can be charged by a lead wire connected to the base, but in the case of a secondary battery, a charging circuit is required, which tends to increase in size and cost. When the merchantability is affected, a primary battery such as a lithium button battery capable of supplying power without any problem may be applied as the power source for lighting the auxiliary light source.

  The power supply switching means is a switch configuration configured to open and close a contact provided in a circuit that supplies power from the battery means, and the power supply switching means is provided with a control unit disposed on the outer surface of the base. Yes. The electric power from the battery means can be turned on / off by the operation of the controller.

  The fluorescent lamp with an auxiliary light source according to claim 2 is attached so that a control part of the power supply switching means protrudes from the base, and this control part is connected to a socket for supplying electric power from a lighting device for lighting the fluorescent lamp. In some cases, the power opening / closing means operates to turn on the power from the battery means by being pushed into the base by the socket.

  The lighting fixture of Claim 3 is a lighting fixture main body; The fluorescent lamp with an auxiliary light source of Claim 1 or 2 attached to this lighting fixture main body; The lighting device which mainly lights this fluorescent lamp with an auxiliary light source; It is characterized by having

  According to the fluorescent lamp with an auxiliary light source of the first aspect, the lamp is lit by discharge of the glass bulb in a normal state. When an earthquake occurs, the vibration detection means of the auxiliary light source lighting device housed in the base detects the vibration and operates to turn on the auxiliary light source by the power of the battery means. For this reason, a fluorescent lamp with an auxiliary light source that can secure a minimum illuminance that can start disaster prevention actions even if an earthquake occurs while the lamp is extinguished, is easy to install, and is relatively small and inexpensive. Can be provided. Also, since the power supply switching means that operates to control on / off of the power from the battery means is provided on the outer surface of the base, at least if the power switching means is turned off before the start of lamp use, the auxiliary light source can be used during transportation. Can be prevented from malfunctioning, and standby current consumption can be reduced when the lamp is not in use.

  According to the fluorescent lamp with an auxiliary light source of claim 2, when the connection terminal is connected to the socket for supplying power from the lighting device for lighting the fluorescent lamp, the power supply opening / closing means projecting from the base by the socket is provided on the base. By being pushed inward, the power supplied from the battery means operates so as to be turned on / off, so that the power opening / closing means can be reliably turned on when the lamp is used.

  According to the third aspect, it is possible to provide a lighting apparatus including the fluorescent lamp with the auxiliary light source.

A protective film made of fine particles and a phosphor layer made of phosphor of a three-wavelength emission type are formed. A filament electrode (not shown) as an electrode is disposed at both ends of the glass bulb 2, and straddles between both ends of the glass bulb 2. The base 3 is disposed so as to cover both ends. Here, the annular fluorescent lamp 1 is of the 32W type, and the glass bulb 2 has an annular outer diameter of about 299 mm and a tube outer diameter of about 29 mm.

  The base 3 has a hollow cylindrical shape and is formed of a heat-resistant synthetic resin member made of PBT or polycarbonate, and forms a part of an annular shape continuously with the annular shape of the glass bulb 2 to form a slight arc. It is formed in a substantially cylindrical shape.

  The base 3 is divided into two parts with a surface along the central longitudinal direction as a boundary, and forms a semi-cylindrical first divided body 3a and a second divided body 3b, respectively. The first divided body 3a and the second divided body 3b are combined so as to come into contact with each other, and the first divided body 3a and the second divided body 3b are positioned by fitting means (not shown). Are connected with screws. Four base pins 3c electrically connected to the electrodes are projected from the outer surface of the first divided body 3a of the base 3. The second divided body 3b of the base 3 has an auxiliary light source 4 · ... 4. A slide switch 5 and an auxiliary light source lighting device 6 as power supply opening / closing means are provided. Furthermore, an operation portion 5a as a control portion of the slide switch 5 is provided on the outer surface of the second divided body 3b so as to protrude. The slide switch 5 is accommodated in the second divided body 3b. Auxiliary light source 4 ... 4 is composed of four white light emitting diodes 4 molded with a bullet-shaped resin lens, and the direction opposite to the base pin 3c (the direction of the illuminated surface of the lighting fixture) It is arranged outside the second divided body 3b of the base 3 so as to face. The slide switch 5 has an operating portion 5a protruding from the outer surface of the second divided body 3b of the base 3. By manually sliding the operating portion 5a, the power supply to the auxiliary light source lighting device 6 is turned on. • It is configured to switch off.

  As shown in FIG. 2, the auxiliary light source lighting device 6 includes a battery means 61 composed of a lithium button battery, a vibration detection means 62 composed of a vibration switch, a timer circuit 63 composed of a CR time constant circuit and an IC circuit, a transistor, etc. Switch means 64, and power supply opening / closing means 5 capable of turning on / off the power supplied from the battery means 61 to the vibration detection means 62 and the timer circuit 63. The auxiliary light source lighting device 6 is unitized by mounting each component including the battery means 61 on a board, and is attached to the inside of the base 3b. The auxiliary light source 4 is connected to the battery means 61 of the auxiliary light source lighting device 6 via the switch means 64, and the on / off operation of the switch means 64 is controlled by the output of the timer circuit 63.

  According to the annular fluorescent lamp 1 with an auxiliary light source according to the first embodiment, the auxiliary light source 4 is configured to be turned on even when a power failure occurs when vibration at the time of an earthquake is detected. Thus, it is possible to provide a fluorescent lamp for earthquake countermeasures that can secure the minimum illuminance that can be achieved and that is easy to mount while maintaining the size of a conventional fluorescent lamp. In addition, since the auxiliary light source 4 is attached to the base 3, the attachment of the auxiliary light source 4 does not increase the size of the lamp. Furthermore, since the slide switch 5 capable of turning on / off the power supplied from the battery means 61 is provided on the base 3, the user turns off the power from the battery means 61 except when the fluorescent lamp is used. It is possible to prevent the battery means 61 from being consumed more than necessary due to the lighting of the auxiliary light source 4 due to malfunction or the consumption of standby power other than when the lamp is used. Furthermore, since the slide switch 5 is disposed in the second divided body 3b of the base 3, when the fluorescent lamp 1 is mounted on a lighting fixture, the operation portion 5a of the slide switch 5 is relatively moved from the irradiated surface side. As a result, the slide switch 5 can be easily turned on / off even when the lamp is mounted on the instrument. For this reason, even when there is intentional vibration such as when cleaning the instrument or when the user is absent for a long time, the standby power can be easily turned off by operating the slide switch 5 with the fluorescent lamp mounted on the instrument. In particular, when the battery means 61 is a primary battery, the power consumption can be reduced and the life of the battery means 61 can be extended. Furthermore, since the auxiliary light source unit including the auxiliary light source 4, the slide switch 5 and the auxiliary light source lighting device 6 is attached to the second divided body 3b, the connection pin 3c and the lead wire are connected to the first divided body 3a. After the connection, the second divided body 3b containing the auxiliary light source unit can be attached and the base 3 can be assembled, and the lead wire connecting process and the base 3 assembling process can be simplified.
